---------------------------------------
Summary: Unexpected exception thrown when FlowMap is injected on a
RequestScoped bean
Key: MYFACES-4127
URL: https://issues.apache.org/jira/browse/MYFACES-4127
Project: MyFaces Core
Issue Type: Bug
Affects Versions: 2.3.0-beta
Reporter: Eduardo Breijo
Priority: Minor
When @FlowMap is injected on a RequestScoped bean, and you try to use that
object (which should be null since we are not inside of a flow), an unexpected
exception is thrown.
Caused by: org.jboss.weld.exceptions.IllegalProductException: WELD-000052:
Cannot return null from a non-dependent producer method: Producer for Producer
Method [Map<Object, Object>] with qualifiers [@FlowMap @Any] declared as
[[UnbackedAnnotatedMethod] @Produces @FlowMap @ApplicationScoped public
org.apache.myfaces.cdi.faces.ApplicationScopeObjectProducer.getFlowMap()]
declared on Managed Bean [class
org.apache.myfaces.cdi.faces.ApplicationScopeObjectProducer] with qualifiers

On Mojarra 2.3, we get a different exception which looks more appropriate.
